【摘要】 基于HRB400级钢筋混凝土柱的试验,对其滞回性能进行分析与研究,并对其损伤程度进行评价.通过比较两种不同的损伤模型,建议采用一个基于延性系数的损伤模型.为了找出结构(构件)的延性系数,根据试验的结果建立了其与累积滞回耗能的关系图.针对4个HRB400级钢筋混凝土柱的试验数据拟合结果,提出计算累积滞回耗能的方法.更多还原

【Abstract】 Based on the experiments of HRB400 grade reinforced concrete columns,the hysteretic behaviors is analyzed,and the damage degree is evaluated.Comparing two types of damage model,it is proposed to adopt the model based on the ductility coefficient.In order to obtain the ductility coefficient,the relationship between the coefficient and cumulated dissipated hysteretic energy is built according to the experimental results.Based on the data fitting results of four columns,the method to calculate the cumulated dissipated hysteretic energy is put forward.更多还原
